I bought an older SFU unit from ebay, which I managed to get working. But it has two bugs that I would like to fix.
1. After unplugging it at boot time, it prints: CMOS checksum error - Defaults loaded. Is the DC battery on the mainboard faulty? Or something else? Where is the battery? I have cleaned the unit, but the battery is nowhere to be found.
2. A rubber button just below the screen is not working. Is it possible to buy a new set of buttons or an old front panel somewhere? I have had no success on eBay!
Is there any *pdf service documentation for this unit? If so, I would be grateful if you could send it to me by post: oliverwirthg@aol.com
Thank you very much!
